Cardiac event monitors

Definition

心脏事件监测器是一种记录心脏电活动(ECG)的装置。. This device is about the size of a pager. It records your heart rate and rhythm.

当您需要长期监测少于每天发生的症状时，使用心脏事件监测器.

Alternative Names

Ambulatory electrocardiography; Electrocardiography (ECG) - ambulatory; Continuous electrocardiograms (EKGs); Holter monitors; Transtelephonic event monitors

How the Test is Performed

Each type of monitor is slightly different, 但大多数都有传感器(称为电极)来记录你的心电图. 在一些模型中，它们通过粘性贴片附着在你胸部的皮肤上. The sensors need good contact with your skin. Poor contact can cause poor results.

你应该让你的皮肤远离油脂、面霜和汗水(尽可能多)。. 放置监护仪的技术人员将执行以下操作以获得良好的心电记录:

• 男性将在放置电极贴片的胸部区域剃光.
• 在连接传感器之前，将用酒精清洗电极连接的皮肤区域.

你可以携带或佩戴心脏事件监测器长达30天. 你可以把它拿在手里，戴在手腕上，或者放在口袋里. 事件监控器可以佩戴数周或直到出现症状.

There are several types of cardiac event monitors.

• Loop memory monitor. The electrodes remain attached to your chest, and the monitor constantly records, but does not save, your ECG. 当你感觉到症状时，你按下一个按钮来激活设备. 该设备将保存前不久的心电图, during, and for a time after your symptoms begin. 一些事件监测器如果检测到心律异常就会自动启动.
• Symptom event monitor. 这个设备只在症状出现时记录你的心电图，而不是在症状出现之前. 你可以把它放在口袋里，或者戴在手腕上. When you feel symptoms, 你打开这个设备，把电极放在你的胸口来记录心电图.
• Patch recorders. This monitor does not use wires or electrodes. 它使用贴在胸口的贴片连续监测心电图活动14天.
• Implanted loop recorders. 这是一个小监视器，被植入胸腔的皮肤下. 它可以留在原地监测心律3年或更长时间.

While wearing the device:

• 您应该在佩戴监视器时继续正常活动. 您可能会被要求在测试期间进行锻炼或调整您的活动水平.
• 把你戴着显示器时所做的活动记下来, how you feel, and any symptoms you have. 这将有助于您的医疗保健提供者将症状与您的监测结果相匹配.
• 监测站的工作人员会告诉你如何通过电话传输数据.
• 你的十大赌博平台排行榜会查看数据，看看是否有异常的心律.
• 监测公司或订购监测器的供应商可能会与您联系，如果发现有关的节奏.

While wearing the device, 您可能会被要求避免某些事情，可能会破坏传感器和监视器之间的信号. These may include:

• Cell phones
• Electric blankets
• Electric toothbrushes
• High-voltage areas
• Magnets
• Metal detectors

向安装设备的技术人员索取一份要避免的事情清单.

How to Prepare for the Test

如果您对任何胶带或其他粘合剂过敏，请告知您的十大赌博平台排行榜.

How the Test will Feel

This is a painless test. 然而，电极贴片的粘合剂可能会刺激您的皮肤. 一旦移除补丁，这种情况就会自行消失.

You must keep the monitor close to your body.

Why the Test is Performed

大多数情况下，在症状频繁的人群中，一项名为 Holter monitoring，持续1至2天，在使用心脏事件监测仪之前进行. 只有在没有诊断结果时才订购事件监视器. 事件监控器还可用于出现较少症状的人员, such as weekly to monthly.

Cardiac event monitoring may be used:

• To assess someone with palpitations. 心悸是一种感觉，你的心脏跳动、加速或不规则地跳动. They can be felt in your chest, throat, or neck.
• To identify the reason for a fainting or near fainting episode.
• To check the heartbeats in people with risk factors for arrhythmias.
• To monitor your heart after a heart attack or when starting or stopping a heart medicine.
• To check if a pacemaker or an implantable cardioverter-defibrillator is working properly.
• 当其他检查方法无法轻易发现中风的原因时，寻找病因.

Normal Results

Normal variations in heart rate occur with activities. 正常的结果是心脏节律或模式没有明显的变化.

What Abnormal Results Mean

Abnormal results may include various arrhythmias. 这些变化可能意味着心脏没有得到足够的氧气.

It may be used to diagnose:

• Atrial fibrillation or flutter
• Multifocal atrial tachycardia
• Paroxysmal supraventricular tachycardia
• Ventricular tachycardia
• Slow heart rate (bradycardia)
• Heart block

Risks

除了可能的皮肤刺激外，该测试没有任何风险.
